Can anyone confirm the torque figures for the heat exchanger to head nuts? I have initial torque at 7.3 ft/lb and final torque at 24.5 ft/lb.

Annealing makes the copper "dead soft". In theory, that allows it to conform to the area that it is sealing better. I'm not sure how much good it does in practice, but it's a pretty simple extra step that shouldn't do any harm...
